Idol group Block B is making a comeback after 8 months.

On October 17, Block B announced that they would be releasing a new album with a 'pirate' concept. The album has a total of 12 songs and their title song is called, "NILLILI MAMBO."

Their agency commented, "The group has taken time off and have been volunteering and taking character education classes. Their new album has already been gaining much attention and we are planning to make more copies soon."

Their title song features an addictive and strong hip-hop beat.

Block B had temporarily stopped their activities after the crisis in Thailand back in February.
